HOW/WHY?

I'm quite accustomed to the concept of Morrison's Wonky Veg. (I'll give them an apostrophe; position up for discussion)  Parsnips, for instance, which would be passed over in the typical Supermarket beauty/conformity contest; e.g. Parsnips - too BIG, too tiny, a bit wiggly, etc. in NO way affects the flavour.  I'd LOVE to know what a Peaa needs to be like to be judged "Wonky".
